An Introduction to Junk Files

Before we jump into the methods of removing junk files, let’s get an idea about junk files. Each and every application installed on your Mac has these junk files. They can be found in a specific folder.

Some of the junk files are temporary, and they appear and disappear pretty often within the system.

One of the major issues with junk files is that they can be invisible to regular users. As a result, they can grow into a huge pile, and your system will not use them again.

Like any other file in your Mac, junk files need some space to sit on. So, as the number increases, these junk files can easily accommodate a large space of your storage device. As you download files and install applications, the number of junk files can increase rapidly.

Sometimes, they may be present in the form of cache or temporary files in the system. Pretty often, for many users, locating and deleting these junk files have become a very serious challenge. Doing it manually can take a considerable amount of time and still deliver not-so-impressive results.

So, plenty of Mac users tend to rely on special applications that are developed to remove junk files. CleanMyMac is one of those applications that can remove junk on Mac files effectively.
